Prior to the step S110, the mobile terminal 100 and the other electronic device 200 may form a communication link through the first communication means. For example, the mobile terminal 100 may form an NFC link by tagging the NFC communication module 220 included in the other electronic device 200, as shown in FIG.

The mobile terminal 100 may transmit a handover request message, for example, a handover request message to the other electronic device 200 through the NFC link in a state where the NFC link is formed.

The mobile terminal 100 transmits the handover request message to the other electronic device 200 so that the mobile terminal 100 and the other electronic device 200 can communicate with the mobile terminal 100, It is possible to initiate a protocol for forming another communication link through the NFC link formed between the electronic devices 200. [

Here, the mobile terminal 100 may have a status of a handover requester, and the other electronic device 200 may have a status of a handover selector. The handover requestor refers to a device that initiates a handover protocol by transmitting a handover request message to another NFC electronic device. The handover selector configures a handover selection message as a response to the received handover request message You can say the NFC device that responds.

That is, the handover requestor (i.e., the handover requesting device) and the handover selector (i.e., the handover selection device) are relative concepts determined according to whether the handover request message is transmitted or the handover selection message is transmitted. Accordingly, when the other electronic device 200 transmits the handover request message to the mobile terminal 100, the mobile terminal 100 becomes a handover selector and the other electronic device 200 May be a handover requestor.

The handover request message may include information on another communication module supported by the mobile terminal 100. [ 4, when the mobile terminal 100 supports Bluetooth and Wi-Fi, the handover request message includes information about Bluetooth and Wi-Fi supported by the mobile terminal 100. For example, .

The priority of the communication technology supported by the mobile terminal 100 used for the handover may be predetermined. For example, as shown in FIG. 4, the handover request message includes information on a communication module supporting a communication technology having a high priority, and a communication module supporting a communication technology having a low priority Information can be written on the back. Referring to the handover request message shown in FIG. 4, it can be seen that the information on the Wi-Fi communication module has a higher priority than the information on the Bluetooth communication module.

The other electronic device 200 having received the handover request message may transmit a response to the handover request message to the mobile terminal 100 (S120). For example, the other electronic device 200 generates a handover selection message as an example of a response to the handover request message through an NFC link, and transmits the generated handover selection message to the mobile terminal 100 ).

The other electronic device 200 analyzes the handover request message to determine what is in the communication module included in the mobile terminal 100 and transmits the handover request message to the mobile terminal 100 The information about the communication module included in the communication module 200 can be provided. That is, the information on the communication module included in the handover selection message may include information on the communication module included in the other electronic device 200 among the communication modules included in the mobile terminal 100.

4, the controller 210 of the other electronic device 200 analyzes the received handover request message to transmit the Bluetooth communication module 118 and the Wi-Fi communication module 119 to the mobile terminal 100 And then transmits a handover selection message including information on the Bluetooth communication module 230 and the Wi-Fi communication module 240 included in the other electronic device 200 to the mobile terminal 100 .

The control unit 180 of the mobile terminal 100 analyzes the handover selection message and transmits the handover selection message to the Bluetooth communication module 230 of the other electronic device 200. [ And the Wi-Fi communication module 240 are included, and information about the Wi-Fi communication module 240 can be acquired.

Then, the mobile terminal 100 establishes a communication link with the communication modules included in the other electronic device 200 based on the acquired information, and then transmits the communication link to the other electronic device 200 200) (S120).

For example, the controller 180 of the mobile terminal 100 may perform Bluetooth pairing with the other electronic device 200 to change the NFC communication link with the other electronic device 200 to a Bluetooth communication link . Accordingly, the mobile terminal 100 can switch the communication link with the other electronic device 200 from the NFC communication link to the Bluetooth communication link to continue communication according to the Bluetooth protocol.

As the communication link between the mobile terminal 100 and the other electronic device 200 is handed over from the NFC communication link to the Bluetooth communication link, the mobile terminal 100 and the other electronic device 200 are no longer in the state shown in FIG. 4 It is possible to perform data communication even if it is not located within the NFC communication range shown in FIG. 4A, and data can be exchanged at a higher transmission rate than the NFC link.

In other words, when the mobile terminal 100 is a smart phone, the user brings the smartphone near the other electronic device 200 and performs tagging with the other electronic device 200 to form an NFC link, By performing the over protocol, the communication means can be changed over the Bluetooth communication link. Then, even if the user takes out the smart phone out of the NFC communication range, the smart phone and the other electronic device 200 can continue data communication through the Bluetooth communication link.

The control unit 180 of the mobile terminal 100 performs a process of forming a WiFi communication link with another electronic device 200 in order to change an NFC communication link with the other electronic device 200 to a WiFi communication link, And may perform data communication with the other electronic device 200 through the formed WiFi communication link. Then, the mobile terminal 100 can perform data communication with the other electronic device 200 even outside the NFC communication range at a higher data transmission / reception rate than the NFC communication link.

At this time, when there are a plurality of changeable communication links from the NFC communication link, the control unit 180 of the mobile terminal 100 may perform a handover for only the selected communication link among the plurality of communication links, Lt; / RTI > In addition, when the controller 180 selects a communication link for performing a handover among a plurality of communication links, the controller 180 may select a communication link according to a predetermined priority order.

3 and 4, when the mobile terminal 100 according to the present invention transmits a communication link (for example, an NFC communication link) with a communication module included in another electronic device 200 to the other electronic device 200 (E.g., a Bluetooth communication link, a Wi-Fi communication link) with another communication module included in the wireless communication module.

Hereinafter, the mobile terminal 100 according to an embodiment of the present invention forms a communication link with a data storage element storing information on a communication module included in another electronic device, and then transmits the formed communication link to the other A process of handing over to a communication link with another communication module included in the electronic device will be described.

5 shows another example in which the mobile terminal 100 forms a communication link with another electronic device 200 according to an embodiment of the present invention. Referring to FIG. 5, the mobile terminal 100 includes a first communication module 110A, a second communication unit 110B, and a controller 180. 5, only the configuration necessary for explaining the communication link forming characteristic of the mobile terminal 100 is shown in a simplified manner as in FIG.

The other electronic device 200 includes a control unit 210 and a communication unit 250. The controller 210 may control the operation of the other electronic device 200 as a whole. The communication unit 250 may include a plurality of communication modules such as a first matching communication module 251 and a second matching communication module 252 used to form a plurality of second communication links with the mobile terminal 100 have.

The first communication module 110A may form a first communication link with the data storage device 225 under the control of the controller 180. [ For example, when the distance to the data storage device 225 is shorter than a predetermined distance, the controller 180 controls the first communication module 110A to form a first communication link with the data storage device 225 can do. If the data storage element 225 is an NFC tag, the first communication module 110A may form an NFC communication link with the NFC tag by NFC tagging under the control of the controller 180. [ Meanwhile, in the embodiments of the present invention, the data storage device 225 may be an NFC tag, an RFID tag, a barcode label, a QR code label, or the like, and may include various devices to be implemented in the future have.

The data storage element 225 may store data necessary for setting the first communication link. For example, the data storage element 225 may store link setting information used to form an NFC communication link with the mobile terminal 100. 5, the data storage device 225 is separate from the other electronic device 200, but according to an embodiment of the present invention, the data storage device 225 may be included in the other electronic device 200 .

In addition, the data storage element 225 may store link setting information for forming a second communication link with the other electronic device 200. For example, the data storage device 225 may include information on a communication module included in the other electronic device 200.

Then, the control unit 180 of the mobile terminal 100 determines whether or not the information about the communication module included in the other electronic device 200, which is received from the data storage device 225 via the first communication link, So as to form a second communication link with the other electronic device 200.

The second communication unit 110B may form a plurality of second communication links with the other electronic device 200 under the control of the controller 180. [ For example, the second communication unit 110B may form a plurality of communication links including the Bluetooth communication link, the Wi-Fi communication link, and the Zigbee communication link with the other electronic device 200 under the control of the controller 180 . As shown in FIG. 5, the second communication unit 110B may include a plurality of second communication modules 110B1 and 110B2.

At this time, at least one of the plurality of second communication links may have a communication range than the communication range of the first communication link. For example, if the first communication link is an NFC communication link and at least one of the plurality of second communication links is a Bluetooth communication link, the mobile terminal 100 may be able to communicate with the other electronic device via the Bluetooth communication link, And can perform data communication with the device 200.

It is also preferred that at least one of the plurality of second communication links has a bandwidth that is greater than the bandwidth of the first communication link. For example, if the first communication link is an NFC communication link and at least one of the plurality of second communication links is a Wi-Fi communication link, then the mobile terminal 100 may use the Wi- And can perform data communication with the other electronic device 200.

The control unit 180 forms a second communication link of one of the plurality of second communication links based on first link setting information received from the data storage device 225 via the first communication link, And the remaining second communication link of the plurality of second communication links may be sequentially formed according to a predetermined priority.

In the process of forming the remaining second communication link after the one communication link is formed, the control unit 180 controls the second link, which is used for forming another second communication link, Configuration information can be shared. Then, the control unit 180 may form the second different communication link with the other electronic device 200 based on the shared second link setting information.

For example, when the first one of the plurality of second communication links is formed based on the first link information received through the first communication link with the data storage element 225, The second link setting information used for forming the second second communication link may be shared with the other electronic device 200 through the first second communication link. When a second second communication link is formed, the controller 180 transmits second link setting information used for forming a third second communication link to the other electronic device (for example, 200).

Therefore, the user of the mobile terminal 100 according to the present invention performs only an operation (e.g., NFC tagging operation) for forming a first communication link with the data storage element 225, A plurality of communication links between the base stations 200 can be formed at the same time. That is, a user of the mobile terminal 100 according to the present invention can transmit a plurality of second communication links of the mobile terminal 100 and the other electronic device 200 without inputting information for forming a plurality of second communication links .

Then, the control unit 180 receives the link information received from the data storage device 225 through the first communication link (S220). The link information may be information on one of a plurality of communication modules included in the other electronic device 200. [

When the link information is received, the controller 180 forms one of the plurality of second communication links based on the received link information (S220). Meanwhile, when the link information is received, the control unit 180 may activate a plurality of communication modules included in the mobile terminal 100 as a preparation step for forming the plurality of second communication links.

16 is a flowchart showing another method of managing a plurality of communication links formed between the mobile terminal 100 and another electronic device 200 according to an embodiment of the present invention. Hereinafter, the plurality of communication link management methods will be described with reference to necessary drawings.

The controller 180 of the mobile terminal 100 controls the communication modules included in the mobile terminal 100 to form a second communication link with the other electronic device 200 and a third communication link S1000. If the second communication link and the third communication link are formed, the controller 180 checks the power state of the mobile terminal 100 (S1010).

Then, the control unit 180 determines whether the remaining power of the mobile terminal 100 is equal to or less than a predetermined threshold value (S1020). If the remaining power of the mobile terminal 100 is less than or equal to the threshold value, the controller 180 may deactivate any one of the second communication link and the third communication link. At this time, the deactivated communication link may be a communication link that consumes more power than the other communication link.

For example, when the remaining power of the mobile terminal 100 is determined to be below a certain level in a state where a Bluetooth communication link and a Wi-Fi communication link are formed between the mobile terminal 100 and the other electronic device 200, 180 may deactivate a Wi-Fi communication link with a relatively high power consumption, and may perform data communication with the other electronic device 200 via a Bluetooth communication link.
